PAPER-STOCI'LTILEATING MACHINE.

Specication of Letters Patent.

Patented Aug. 27, 1918.

To all 'whom it mag/ concerm 'Be it known that I, MILTON C. J. Birma@ HAM, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements iii Paper-StockTreating Machines, of which the following is a specification.

This invention relates to improvements in pa yr stock treating machines.

`he main objects of this invention are:

First, to provide an improved stock treating machine for washing and disintegrating paper stock which is of verylarge capacity.

becond, to provide an improved machine for washing and disintegrating paper stock which greatly reduces the time commonly required for washin paper stock.

Third to rovi e an improved machine of the class escribed which is adapted for use in de-inking and disintegrating printed paper for use 4as aper stoc Fourth, to provide an improved machine of the class Vdescribed which produces a' siiperiorproduct.

Further objects, and `objects relating tu structural details, 4will definitely appear cured forwardly cui-'ved blades 9, the blades from the detailed description to follow.

I accomplish the'objects of 'my invention by the devices and means described in the following specification. The invention is -clearly defined and ointed out in the claims.

A structure whic `is a preferred embodiment of my invention 4is clearly illustrated in the accompan in drawing, forming a part of this speci ca ion, in which:

Figure I is a rear en d elevation of n striicture embodying the features of my-invention.

F ig. II is a front end elevation.

Fig. III is a detail plan view of the rear end of the structure. Fig. IV is a detail longitudinal section on a line corres riding to line44 of Figs. I, II, III and full lines.

Fig. V is a transverse section on a line corresponding to line 5-5 of Fig. IV:

Fig. VI is ancnlarged transversedetail'- section showing details of the cylinder structure.

Fig. VII is a detail view partially in transverse section of the agitator shaft.

Fig. VIII `is a detail transverse section on a line corresponding to line 8-8 of Fig. IV.

, the parts being' shown in 4ap outlet 14 Fig. 1x is a. demi longitudinal seccion of a modified embodiment of my invention.

Fig. X is a transverse section of another modified form` or embodiment of my invert-` tion.

Fig. XI is a detail section on aline corresponding to line 11-11 of Fig. X.

Fig. II is a lan view of another modiication provid with means for refpassing the stock through the machine. i

In the drawing` similar reference chai-` acters refer to similarparts'throughoutlthe several views, and the sectional views are taken looking in the direction of the' little'.

arrows at the ends of the section lines. z. Referrin V trough 1 o such size as to receive the cylinder 2 which is rotatably mounted therein. The ends of the trough are rovidedzwith bearings cylinder.

The body walls 5 of the cylinder are fo` raminated. Within the cylinder is a spiral 6 having a rearward lead, the s iral being for conveniencein manufacture, uilt up oi to the drawing, I provide a'.

3 for the tubular gu geons 4 of the segments 7. Between these .segments are. l

longitudinal bars 8.- To these barsare seder revolves, carry the stock up to the pointwhere it is discharged by gravity from the clippers.

ithin the spiral I provide a series of compartments 10 havin inlet openings 11 into which thestock is` ischarged from the blades. These compartments have discharge openings 12 on the downstroke side of -the cylinder. As the cylinder revolves it carries the stock up and discharges it into the compartments fronrwhich it overflows into the cylinder. These s irally arranged dippers discharge the stoel; to succeedin compartments so that it is repeatedly passe through the compartments and discharged therefrom and advanced towardthe rear of the cylinder. i. z

At the rear of the cylinder I provide a disiosdippersdi'sc argethereto. This trough' has 16 ehvering to the conveyor Pl .9

isposed axially of 'the cylinder an through the compartments and trou h is a shaft 16 having propeller-like bla es 17 thcreon arranged within the compartments so that. the stock is violently agitated within the confined area of these compartments to break u lumps of stock or disintegrate the same. he stock being passed through rcpeated compartments is subjected to a'scrie's of disintegrating and washing operations.- The lengt-h of the machine may, of course, be varied as circumstances render desirable.

()n the shaft 16 is a discharge screw 18 which drives the stock from thc trough into the discharge spout or pipe.

To prevent clog ing of the cylinder and also to further isintegrate the stock I provide a spray pipe 19 positioned so as to spray the stockas it is discharged from the dippers. To further break ug and wash the stock I provide sprays 20 an 21 positioned so as to discharge against. the stock or across the path-of the stock as it is discharged by the dippers into the compartments.

I also preferabl provide a spray 22 positioned so that it ischarges across the path of the stock as it is delivered from the com partments. Thesesgrays not only assist in washing the stock ut also in disintegrating it.

To facilitate cleaning of the apparatus the shaft 16 is preferably 1n the form of a pipe having spra openings 23. Water may be discharged t, rough this pipe whileoperting on stock. ,The stockls'dolivered to the machine through the pipe 24.

cation shown in Fi IX the ds ira. ybut the In the-mod dippers 25 are not dis 'compartments26 are ispose diagonally so that the st'okin passing through the compartmcnts' is'pa'dvanced one ste 'as it dischargesl from the compartments into the succ'eedin 4an'nula"r f.j,series of'dippers.'

In tlie modification 'shown in Figs. X and XI the lieetelsl Qrfagitating blades are omitted, th'structiire' being especiall designed us a washer, thd'disintegrating' eatin-es of the blades being omitted. In this structure thc dippers discharge across the inclined rorrugatedplate .27 having a series of spray pipes 2R discharging across the' ath of the slot-k. The means for driving t c cylinder und the shaft form no part of this invention. Th'ey are conventionally illustrated but I do not deem it necessary to describe the same herein.

In Fig, XII I show means for repeatedly passing the stock through the machine which is sometimes i'lcsirahlv. especially in (le-inlcingV processi-s. In this conssruction thc discharge pipe 29 delivers thc .stock to a tank 30 from which it is returned to th machine through the pump 3l. The pump nud a driving motor 32 are shown convcnllfmally.

My improved paper stock treating l...| chine isvery eflicicnt for washing and disintegrating paper stock and has also n very large capacity, it being capable of handling much greater quantities of stock in a given time thanl the ordinary washer now com- -nionly emplo 'ed. The structure is also advantageous or use in de-inking processes as it is effective in breaking up or disintegrating paper and like material into their separate fibers` I have illustrated and described my improvements in certain embodiments which I contemplate and which I believe will enable the adaptation of my improvements to the various uses for which they are desirable by those skilled in the art to which this invention relates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent., is:
